Bone Tales

Author(s):  
Gabriela Nouzeilles

This chapter focuses on visions of Patagonia as the origin of the world in the work of the renowned Argentine scientist Florentino Ameghino (1854–1911), and particularly on his recourse to indigenous myth in the development of his (later discredited) theories of biological evolution. In the fin-de-siècle ‘bone rush’ in Patagonia, fossils became monuments of national wealth and a staging-ground for the battles of evolution between fossilized tribes. This scientific re-reading of the landscape questioned dominant narratives of prehistory, placing Patagonia not at the end of the world but at its origin. Ameghino’s fossils, often bigger and more complete than those of North America or Europe, provide the foundation for a strategic inversion of such narratives, constructing Patagonia as the site of the monumental ruins of a glorious past of biological supremacy. His theories of racial evolution were later disproved, but his work demonstrates the power of the paleontological imagination in constructing discourses on race in South America and beyond. Moreover, Ameghino’s hybrid brand of naturalism, which combines indigenous mythologies with Western knowledge, represents a fascinating example of how histories of local geographical and archaeological discourses developed at the dawn of the twentieth century.

The genus Atriplex Linnaeus (1753: 1052) (Chenopodiaceae Vent.; placed in Amaranthaceae Juss. s. l. in APG IV 2016) comprises about 300 species distributed mainly in subtropical, temperate, and subarctic regions of the world and is mostly adapted to dry conditions on often saline soils (Sukhorukov & Danin 2009, Kadereit et al. 2010, Iamonico 2013, APG IV 2016). The genus is highly diverse in Eurasia, Australia and North America. South America is another centre of diversity with ca. 55 species, 45 of which are considered as native (Brignone et al. 2016). A recent and exhaustive taxonomical synopsis of Atriplex for South America was published by Brignone et al. (2016), but there are also regional taxonomic revisions, e.g., for Chile by Rosas (1989), or Argentina by Múlgura de Romero (1981, 1982 & 1984).

This chapter analyzes the uses and appropriations of scientific discourse in Argentine magazines from the fin de siècle: a period in which literary modernism coincided with the development of spiritualisms that aspired to the status of science (or “occult sciences”) like Spiritism and Theosophy. The aim is to examine concrete examples that relativize the sharp division between science, art, and spiritualism in the culture of this period. The main sources explored are La Quincena. Revista de letras (1893–1899), Philadelphia (1898–1902), La Verdad (1905–1911), and Constancia (1890–1905). In addition, the chapter focuses on how the astonishing growth of science in Argentina, as well as the social legitimation of scientific discourses, influenced other fields, giving shape to new literary expressions, beliefs, and utopian projections that synthesized the material and the spiritual.

Catenulida are mostly inhabitants of freshwater ecosystems, like ponds, streams, though the marine species are few (Larsson and Willems, 2010). About 110 species of catenulids are known worldwide, with most of the studies conducted in South America (Marcus, 1945a, 1945b; Noreña et al., 2005), North America (Kepner and Carter 1931; Nuttycombe and Waters, 1938) and Scandinavian Peninsula (Luther, 1960, Larsson and Willems, 2010; Larsson et al., 2008). The diversity of catenulids from India has not been studied intensively; however some reports on other turbellaria exists for the country (Annandale, 1912; Whitehouse, 1913; Kapadia, 1947; Basil and Fernando, 1975; Apte and Pitale, 2011; Kalita and Goswami, 2012; Venkataraman et al., 2015). The genus Stenostomum, however, has been studied extensively around the world with identification of over 60 species (Tyler et al., 2006-2016). This is first report of the genus from India. The present study was part of the project to catalogue the diversity of free living protozoan ciliates from the Hooghly stretch of the Ganga River during which the flatworms were found. The worms were studied based on the live observations, with recognition of characters which led to its identification. This study serves to fill knowledge gap in the freshwater flatworms from India.

A new basal basilosaurid cetacean, Basilotritus uheni n. gen. n. sp., comes from the late middle Eocene (Bartonian) of Ukraine. It is the earliest dated record of a cetacean from Eastern Europe. The tympanic bulla of Basilotritus uheni shares basilosaurid synapomorphies but possesses unusual traits inherited from protocetids. Cetaceans related to Basilotritus uheni and referred to as Eocetus or “Eocetus” have been recorded from Africa, Europe, North America and South America. “Eocetus” wardii from North America is recombined as Basilotritus wardii. Platyosphys paulsonii and Platyosphys einori from Ukraine are considered as nomina dubia; specimens prior referred to as Platyosphys sp. are similar or related to Basilotritus. Other records of the Eocene cetaceans from Ukraine and south Russia are identified as Basilotritus or related genera. Early basilosaurids are demonstrated to be a paraphyletic, morphologically and geographically diverse group of the genera that colonized the world ocean as late as in Bartonian age and were probably the ancestors of Neoceti, as well as of more derived basilosaurids.

ABSTRACT: According to the World Health Organization, the development of orally replacement fluids and electrolytes was one of the most significant advances of the twentieth century, markedly reducing mortality from diarrheal children. In veterinary medicine, oral electrolyte solutions (OES) are routinely used to treat diarrheic neonatal calves in order to correct water, electrolyte and acid base imbalances. In North America, the use of OES is routine and there are at least 20 commercial alternatives. Use of OES has increased in recent years in Brazil, but just five commercial products are currently available. The OES should contain, in suitable concentrations, electrolytes, glucose and an alkalizing agent to ensure its therapeutic efficacy. This review aimed to address the therapeutic importance of OES for neonatal calves and to evaluate the compositions and characteristics of those commercially available in Brazil.

Abstract Novel Coronavirus (2019-nCoV [SARS-COV-2]) was detected in humans during the last week of December 2019 at Wuhan city in China, and caused 24 554 cases in 27 countries and territories as of 5 February 2020. The objective of this study was to estimate the risk of transmission of 2019-nCoV through human passenger air flight from four major cities of China (Wuhan, Beijing, Shanghai and Guangzhou) to the passengers' destination countries. We extracted the weekly simulated passengers' end destination data for the period of 1–31 January 2020 from FLIRT, an online air travel dataset that uses information from 800 airlines to show the direct flight and passengers' end destination. We estimated a risk index of 2019-nCoV transmission based on the number of travellers to destination countries, weighted by the number of confirmed cases of the departed city reported by the World Health Organization (WHO). We ranked each country based on the risk index in four quantiles (4th quantile being the highest risk and 1st quantile being the lowest risk). During the period, 388 287 passengers were destined for 1297 airports in 168 countries or territories across the world. The risk index of 2019-nCoV among the countries had a very high correlation with the WHO-reported confirmed cases (0.97). According to our risk score classification, of the countries that reported at least one Coronavirus-infected pneumonia (COVID-19) case as of 5 February 2020, 24 countries were in the 4th quantile of the risk index, two in the 3rd quantile, one in the 2nd quantile and none in the 1st quantile. Outside China, countries with a higher risk of 2019-nCoV transmission are Thailand, Cambodia, Malaysia, Canada and the USA, all of which reported at least one case. In pan-Europe, UK, France, Russia, Germany and Italy; in North America, USA and Canada; in Oceania, Australia had high risk, all of them reported at least one case. In Africa and South America, the risk of transmission is very low with Ethiopia, South Africa, Egypt, Mauritius and Brazil showing a similar risk of transmission compared to the risk of any of the countries where at least one case is detected. The risk of transmission on 31 January 2020 was very high in neighbouring Asian countries, followed by Europe (UK, France, Russia and Germany), Oceania (Australia) and North America (USA and Canada). Increased public health response including early case recognition, isolation of identified case, contract tracing and targeted airport screening, public awareness and vigilance of health workers will help mitigate the force of further spread to naïve countries.

This is a fascinating book, partly because of the excellent contributions, and partly because of the ways in which the editors have chosen to engage the topic and organize their volume. Marchand and Lindenfeld open the collection with a loaded question: Was there a German fin de siècle? Did Germans, in other words, share the kinds of reactions to modernity that have so fascinated historians of Austria and France? Their answer is yes and no. Many German intellectuals embraced the modernist currents Carl Schorske identified more than forty years ago in his work on fin de siècle Vienna, reacting to the depressing problems of modernization in ways similar to their Austrian counterparts. And yet much of the German population was largely unbowed by their putatively perplexing condition. As the editors argue, despite the worries of many an intellectual, “the later Wilhelmine world was characterized by enormous ambition and optimism, booming industries and bustling new urban spaces, cultural and political activism on a new scale, and the promise, if not the immediate realization, of a ‘place in the sun’ on the world stage” (p. 1). That optimism is the perplexing bit, because many of us, schooled in the dark side of Weimar culture and its intellectual antecedents, have learned to imagine Germans at the end of the nineteenth century (or at least our favorite representatives) as people caught up in a pessimistic, existential, Nietzschean funk. Indeed, the editors themselves have not avoided that position entirely.

This paper considers the characteristics of satellite television transmission in the world. An overview of the development of satellite television is given through the following characteristics: broadcasting systems - analog and digital (SDTV, HDTV, UHDTV), frequency band (C, Ku, Ka), broadcasting standards (DVB-S, DVB-S2, DigiCipher, DSS), as well as the availability of TV services Free-To-Air TV (FTA) and PAY TV. All of these characteristics were considered both at the global and at the regional level: North America, South America, Europe, Africa, Russia, Asia, and Australia. The gathered data are presented in tabular form and presented graphically for the period from 1996 to 2018. Based on the presented results, an analysis of the development of satellite television transmission was carried out in accordance with the characteristics of the broadcast.
